Description
Thanks to the Openlab program, Oracle and CERN have been working together during several years on database replication technologies used at WLCG. The result of this collaboration is an improvement and notable changes in this area, especially with the introduction of Oracle GoldenGate and Oracle Active Data Guard as a replacement of Oracle Streams. In this poster, we provide an overview of the evolution of database replication technologies since its first deployment in 2007 until 2015 when LHC was restarted for Run2. In particular each replication solution used within WLCG project will be covered with a general description of its features in context of usability for CERN’s use cases as well as the key monitoring tools which combined with Oracle GoldenGate, provides stability within environment replications at WLCG
